Hey Greycloud:
I do not deny that your "know used in place of belief" principle also operates in common usage. It is part of the problem I am talking about (trying to beef up an argument when no real "beef" is to be had).
To me 'belief' is shorthand for 'my current understanding is...
I think you are absolutely right that this is a common usage of the word, among friends who are not trying to grind axes on each other. But in the context of arguments where both sides are trying to "win" an argument at all costs (instead of just finding out what the answer is), that is not what I see going on.
The problem is that "belief" also has this HUGE other side to it: the assumption of "correctness" or "truth" or "reality" is unavoidably bound up with the word "belief." No one would ever intentionally "believe" something that is not true, so the word "belief" is used in reverse, to sort of implicitly try to prove that what is being said is true because someone "believes" it. "No one would believe something that is not true; I believe X, therefore X must be true." This is a caricature of logic, but it is my opinion that it is used by many people in all sorts of arguments all the time. This is usually how "belief" is used in matters that simply cannot be proven one way or the other: religion and politics being famous examples.
If I say that I believe that Homer's Iliad is one of the greatest books ever written, I mean just that.
Perfect example of what I am saying: you are using it in the context of stating an
opinion. You would never say "I believe that the Iliad is a book" because that is a matter of FACT. I have no problem at all when people use the word belief when expressing an opinion. It is when they try to beef up their opinions into a winning argument that I complain. In technical debates where opinions are irrelevant, I say "belief" is thrown in with the hope that some reader or listener will accidentally assume the factual nature of the word (see above paragraph).
Anyway, I have made my point. I think it is obvious when the word "belief" is being abused, and I think it is also obvious that many people are also aware of this. Any thoughtful person whose intent is to get at the truth will not be swayed but the (sole) use of the word "belief," so why use it in serious debates if that is all you've got? If you have evidence, state it. If you don't, avoid the use of the word "belief."
Let's face it: in any serious debate what either side "believes" is irrelevant. The word may be useful in any number of
discussions, but I just don't see how it is helpful in technical debates. That is all I am saying.
And since everything that I am saying is just a matter of opinion, I guess I will fail to sway you to my side, Greycloud
